Serial No. 564,447.

To all whom it may concern:

Be it known that I, JAMES A. Ilnmncn, residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Gas Valves, (it which the following is a specification.

This invention relates to producer gas apparatus, and one of the objects of the invention is to provide new and improved valve mechanism adapted to be used in connection with gas producing and gas consuming apparatus.

Another object is to provide improved means whereby the valve mechanism in such apparatus may be kept in a cool condition at all times and thereby prevented from becoming burned out.

Another object is to provide valve mechanism such that the gas consuming apparatus is at all times in direct communication with the stack, and the gas supplying means is also'in direct communication with the gas consuming apparatus thereby insuring a ready and unobstructed teed of producer gas, and a tree discharge of the products o't combustion.

Another object of? the invention is to so construct the valve mechanism that a ready access may be had to all the interior parts whereby replacement or renewal of parts may be easily and expeditiously e'lt'ectcd.

Other objects will be in part obvious and in part pointed out hereinafter.

lhe invention accordingly consists in the features o't (:(mstruction, combinations of elements and arrangement of parts, which will be exemplified in the construction hereinafter described. and the scope of the application o't which will be indicated in the following claims.

In the accompanying drawings wherein l have illustrated two forms of embodiments of my invention: Figure l is a view in vertical. section of a preferred embodiment thereof, showing); the arrangement of the interior ot the valve mechanism: Fig. 9 is a view in side elevation showing the means for operating the valve in one position; Fig. 23 is a view similar to Fig. 2, but showing the parts in a dilterent position; Fig. -1- is a. view in end elevation, partly broken away; Fig. 5 is a view in perspective (it one of the valves; Fig. (3 is a sectional view showing the manner of conducting water to the valve; Fig. 7 is a sectional view through the casing or cylinder of the valve operating mechanism; Fig. 8 is a vertical sectional view taken substantially on the-line 8-8 of Fig. 7; Fig. 9 is a plan view showing one of the valves and the manner in which the same is mounted within the casing; Fig. 10 is a vertical sectional view showing a slightly modilied embodimentof my invention; and Fig 11 is a view in vertical section on line l1l.l ot the structure shown in Fig. 10.

Similar rc'lerence characters reter to similar parts throughout the several views of the drawings.

Referring now to the drawings, and particularly to the embodiment of my invention shown in Figs. l to 9 inclusive, denotes generally the metallic casing of my improved valve mechanism, in the upper part of which is formed a valve chamber 2, which is preferably lined with a heat resisting material such as shown at 3. Leading into this valve chamber is a conduit 4, which may be valved as by means of the 'alve 5, Fig. l. This conduit leads from a source ol gas supply, not shown. as for instance, :lrom gas producing apparatus. Valve cham her 2 may be provided with an opening (3, through which access may be had to the interior, which opening may be suitably closed as by means at a door 7, held in position in any desirable manner.

Suitably supported upon the side walls 8 and end walls of the casing, are troughs 10, and It indicates a central trough supported upon the upright 12 which is disposed transversely oi the casing, and which in turn is supported by the arch 1st. These troughs are adapted to contain water which is dis charged thereinto by means presently to be described.

15 indicates openings provided in the casing which may be employed as observation openings, or through which access may be had to the interior of the valve-chamber 2, when it is desired to clean out the troughs 10. The outer wall of the vaIve-chamber 12 rests in the troughs l0, and provision is made whereby a slight lateral :uljustment ot' the chamber may be had and by means of the adjusting screws .16, which are threaded into the outer wall of the troughs. The lower edges ot the metallic casing of valve chamber 2 may be cut away, as shown,

below the water line so as to provide for a free access of water to all parts of the trough.

Leading from valve-chamber 2 are pa sage ways 17 and 18 and adapted alter nately to open and close these passage ways is a valve member 20, which is suitably pivoted upon a hollow shaft immediately above trough 14. Valve member 20 is provided with oppositely extending flanges 21 and 22, so that a receptacle adapted for containing water is provided 011 the upper and lower side of the valve member, the flanges adjacent the pivotal portion of the valve memher being provided with openings as at 23, through which water may flow to the trough 11, when the valve member is swung from one side to the other by the means which will presently be described. The shaft 24 which forms a hollow pivot for the valve member 20 is provided with two sets of op posed openings, as at 25, and one of these sets is adapted to register with the openings 27 formed in the collar 28, formed integral with the valve-member and which encircles the pipe upon which it swings, when the valve member is in one position, for instance, as that shown in the drawing whereby water may be discharged through the hollow pivotal portion to the upper portion of the valve. These openings are closed when the valve member is swung to the opposite position to close the passage way 17 and the openings opposite are carried into engage ment with another set of openings in the pipe 24, whereby water may be discharged upon the opposite side of the valve member. The flanges 21 and 22 when the valve memher is in either of its closed positions, dip into the troughs l0 and 11 and form a waterseal for the passage ways 17 and 18.

Passage ways 1? and 18 lead into valvechambers 30 and 31 respectively, which are also provided with suitably closed openings 32 and 33, doors 34 and 35 being provided in the present instance, and these doors 34 and 35 may be provided with suitably closed sight openings 36, 3'7. Leading from valvechamber 30 is a passage way 38 which leads to a conduit 39, and leading from valvechamber 31 is a passage way 40, which leads to a conduit 41. Conduits 39 and 41 are connected with a furnace or other gas consuming apparatus, not shown, and it will be understood that each of these conduits is adapted alternately to conductgas to the gas consuming apparatus, or to conduct the products of combustion therefrom; it being understood that when one of the conduits is conducting gas to the gas consuming apparatus, the other is discharging the products of combustion into a stack, as will be presently described. Leading also from valve-chambers 30 and 31 are passage ways 42 and 43 respectively, which lead into a stack, the

flue of which is shown at 44. Passage ways 42 and 43 are adapted to be closed as by means of valves 45 and 46, and inasmuch as these valves are similar in all respects, but one thereof need be described herein. Referring now to valve 45, the same consists of a metallic sheet provided with opposed flanges 47 and 48, and a downward extending flange 50. The inner end of the valve is formed hollow and is adapted to receive a pipe upon which the same swings, said pipe being provided with suitable openings which register with openings as at 51, and through which water may be discharged upon the top of the valve, it being understood that when the valve is in upright position, the openings are carried out of register thereby shutting off the flow of water. Water may also be discharged on top of the valve as by means of journaled pipes 52 and 53 mounted upon a transversely extending supply pipe 54, the construction being such that when the valves are in a vertical position, water will be discharged through the pipes 52 and 53 by means of the small nozzles 55, carried by said pipes; this result being attained by means of forming valves at the points where the pipes 52 and 53 are connected with the pipe 54, so that when pipes 52 and 53 are vertical the supply of water is turned on, and when they are horizontal, the water is shut off, pipes 52 and 53 being connected with the valve 45, as by means of the strap 56, so as to swing therewith. The flanges 48 and when the valves are in horizontal position dip into troughs 57, 58, the former of which is supported upon an upright and the latter upon the arch 14. It will be understood of course that shafts supporting the valves are hollow only so far as will permit the water to flow out through the eXit orifices, the remainder of the shaft being solid. Valves 45 and 46, in the present instance are each made in two parts and are mounted upon a hollow shaft, the object of this construction being to permit a more ready replacement when necessary. This necessitates the dividing of the passage ways 42 and 43 into smaller passage ways. By this arrangement repairs will be facilitated and the valve will not be so likely to become deformed or cracked. Similar troughs 61 and 62 surround the passage way 43 and a central trough 63 extends parallel with the arch 14, suitable openings as. at 64 being provided to allow the passage of water to flow from the troughs 58 and 61 thereinto.

65 indicates openings adjacent the troughs in the valve chambers 30 and 31, tl rough which access may be had to the interior when it is desired to clean out the troughs. These openings may be closed by any desired means.

Fixed upon the pivot of the valve 20 and located exteriorly of the casing is a 180 segment 66, provided with teeth 67, which mesh with a gear-wheel (S8, journaled upon a pivot (38 fast upon the casing. Fixed upon the pivot of the valve 45, is a 90 segment (if) provided exterior-1y with teeth 70, which mesh with teeth formed upon a gearwheel 71, mounted upon a pivot 72 fast. upon the casing.

73 indicates a reciprocating rack formed with opposed teeth 74 and '75, one set of which meshes with the gear wheel (38, and the other with the teeth upon the gearwheel 71 so that when the rack is moved in a longitudinal direction, the gears (38 and 71. will comn'iunicate the motion to the segments (it; and (i9, and the rotation of the segments will rotate the valves 20 amt 45. The pivotal valve 40 is provided exteriorly ot' the casing with a lever 76, which is connected by means of a link 77, with the segment (it), so that when that segment is retated the said valve 4L6 will be moved in a direction corresponding to the movement of the valve It will be noted that by means of the construction just described, at a given movement of the rack 73, the valve 20 will be moved from one closed position, over one of the passage ways 17 or 18, through an angle of 180 to close the opposite pas sage way, whereas the valves 45 and 46 will move through an angle of about 90, or from open to closed positions or vice versa.

Rack 73 at its outer ends is provided with pistons 78 and 80 suitably packed as at 81, said pistons being adapted to traverse the cylinder Leading into the opposite ends of the cylinder are fluid pressure pipes 83 and 84; through which a fluid may be introduced to operate the pistons. It will be understood that pipes 83 and St may be connected with a suitable source of pressure supply, and that a fluid under pressure may be alternately introduced through said pipes to the opposite ends of the cylinder 82 whereby the rack 73 will be reciprocated, and the valves operated.

Having thus described the construction of this embodiment of my invention, the operation thereof may now be understood. With the parts in the position shown in the drawing gas will flow from the conduit -t through the valve chamber 2, passage way l7, valve chamber 30, passage way 38, and conduit 39 to the gas consuming apparatus, the products of combustion being (.lischarged through the conduit +t1, passage way 40, valve chamber 31, and passage way 43 to the stack M. The ingoing gas is prevented from entering the stack by the valve 45 and the outgoing products of combustion are prevented from entering the valve chamber 2 by the valve 20. W'hen the valves are moved to their opposite positions, the gas will flow from the conduit 4 to the gas consuming apparatus through the valve chamber 9, passage way 18, valve chamber 331, passage way l0, and conduit 4-1., the products of combustion be ing discharged through the conduit 11$), passage way 38, 'alvc-chamber 3t), passage way -12, to the st ack tlue fil'il.

The embodiment of my invention shown in Figs. 10 and 11 is quite similar to that just above described, but: is adapted tor use when a structure o't less height is required. It will be noted that valve-chambers similar to those at 30 and 31. in the first described embodiment are provided at and St; at either side of the valve chamber .2, the gas being received through conduit -.t as in the embodiment first described. Passage ways 87 and 88 lead from valve chamber 2 directly into the conduits 90 aml 91, which are connected with the gas consuming apparatus, and the conduits 92 and 92) extend rearwardly from the valve chambers and 8t} and connect with the stack tlue tl-t, as shown in Fig. 11 ot the drawings as indicated in dotted lines of Fig. 10. .lassage ways 95 and 9t; connect the conduits 9t) and 91 respectively with the valve chambers 85 and 86. A double flanged valve 97 pivoted at 98 is adapted to close both ot the passage ways 87 and 8b, and the passage ways 5)?) and 96 are adapted to be closed by the 'alves 98 and 100. Valves 9?, 9S amt 100 may be connected to move in unison as in the first described embmliment, and watercooling means is shown which forms a seal for the valve as in the embodiment first above described. The operation oi this embodiment of my invention should be largely obvious from the above description and it will be understood that the gas from the source of supply with the parts in the position shown will llow from the conduit l to the valve chamber 2, passage way 88, aml conduit 91, to the gas consuming apparatus and the products of combustion will be discharged throngh the conduit 90, passage way .)5 and conduit )2 to the stack line at. \Vhen the valves are reversed the flow of gas and the products of combustion will be reversed throughout the apparatus.

It will accordingly be seen that I have provided apparatus particularly well adapted to attain, among others, all the ends and objects above pointed out in a simple yet cflicient manner, and as many changes could be made in the above construction and many apparently widely ditt'erent embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accom panying drawings shall be interpreted as illustrative and not in a limiting sense. It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention, which as a matter of language, might be said to fall therebetween.
